Abstract

A mobile communication terminal includes at least one function key which demonstrates improved resistance to vibration. This is achieved by positioning a spacer between the function key and an associated switch, which in the case of a mobile terminal may be a tact switch. The spacer may be made from an elastic material which compresses when inserted between the switch and function key. Alternatively, the spacer may be made from a rigid material. Also, the spacer may extend from one or more layers of a keypad and may be made to bend into proper orientation adjacent a side button on the terminal By eliminating the clearance gap between the function key and switch, undesirable noise is prevented and improved stability to vibration is demonstrated. Also, a better feel to as user is achieved as a result of the reduction or elimination of this clearance gap. <IMAGE>
